Speaking of buzzes/headaches...I had the same thing happen today to me with SB Margarita.
I used a mod bowl (I haven't used this thing in months!) so I decided to use it today.
Oh boy...After my session, I had the huggest headache. I think its because of the fact the bowl gives the tobacco more surface area and that is why I got that headache.
I always chain out my MYA bowl and never had that prob until I used that mod one.
I've NEVER been this sick ever since I was a newbie to hookah.
WHoa it sucked..I felt sick and wanted to throw up(which I didn't) for 2 hours . NOT good times
Best advice is to not take draws one after another or else you will not be happy with the end result
